today I am going to tell you how to calculate how many strips
you can run per power supply.
As the power consumption of the strips related to the power supplies,
I am going to use today the dual density and single density strips compare them
to the 400W power supply as an example. So let me step over to my white board
and I'll tell you the basic math that we use to figure this out. So basically
what I am going to be doing is I am going to tell you

| rgb led strip per power supply |
How to divide the consumption of the strips by the capacity of the
power supply?
All of strips have data sheets which tell you the max consumption at
full intensity. That is for the
RGB and for the whites and all different sets
of strips either 5050, 3528 all of them have amperage consumption data sheet.
So today I am going to talk about the RGB dual density and the RGB
single density. Just to give you a plan on how to do it. And I am going to
compare it all with a 400W power supply. So the dual density strip consumes
right around 48 watts.
Ok and that is at full intensity with all the colors and everything
on all the way. And then the single density consumes exact around 23 watts. Give
or take a watt or two and that is pretty much what it is. I am going to be
using a 400 watt power supply. This right here the 400 watts that is the
capacity of the power supply.
But you never want to run it at full capacity because what you run
risk of getting it too hot and that will shorten the life of your power supply
no to mention other issues that could arise from that.
So now that you know your power supply capacity and how much of it
your strips consume. Then you can form out everything out using very simple
math. So the way you do it you get the capacity of the power supply which is
400 watts.
And then divide by the 48 watts that the strips consume. This is the
48 watts for the dual density strip. Once you do this basic math problem it
comes out to about 8 give or take. So that is 8 dual density strips that you
can put on there.
And you'll like "ok great I can just put 8 of them in there no
problem" right?
But the issue by doing that is that you are going to be running your
power supply at full capacity.
And you know I already talked about the issues with that. So you can
obtain thermal issues and a bunch of other issues that it is best to avoid. So
now that we know 8 is one-hundred percent if we do 6 that will be 75 percent of
your capacity. So I do 6 dual density strips RGB Strips.
Ok.
That will equal to true around 350 watts or so. That right there is
about 75% capacity of the 400 watts which would be perfect to run the strip at.
So 6 strips would be the maximum that you could run safely without running into
any issues or anything like that
So the alike procedure goes for the single density and for pretty
much any other strip. Whether is a 400 watt power supply we also have the 96
watt the 200 watt and the 150 watt water proof power supply. So it is a safe
procedure.
All you got to so is plug-in the numbers. Let's say it's a 96 watt
power supply and you are using single density strips. You put in 96 watt 23
watts down here for the single density and then you get you maximum number and
then you calculate that to get a 75 percentage capacity. 80 percent that is
pushing it.
And that will give you how many strips you can do safely. So that is
attractive much all there is to it. It is a very simple math problem that you
can use. So there is not a whole lot of crazy science or anything like that.
